Description
The TRIAC is a three terminal semiconductor device for controlling current. It gains it’s name from the termTRIode forAlternatingCurrent.
It is effectivly a development of the SCR or thyristor, but unlike the thyristor which is only able to conduct in one direction, the TRIAC is a bidirectional device.
